[0016] The present utility model will be further described below with reference to the drawings.

[0017] As shown in the attached Figures 1 to 4As shown in the figure, a manipulator for grasping the back panel of a TV set includes a manipulator 1, and the manipulator 1 includes a horizontal adsorption unit bracket 2, several fixed adsorption units 3 and an adsorption unit offset device 4; the several fixed adsorption units 3 are installed on the adsorption unit bracket 2 in an array distribution, and the several adsorption units 3 adsorb the back panel of the TV set, so as to realize the grasping of the back panel of the TV set by the manipulator 1; several fixed adsorption units 3 constitute a fixed adsorption unit array 5, and at least one group of floating adsorption units 31 is arranged at one end of the fixed adsorption unit array 5; the adsorption unit offset device 4 can drive the floating adsorption units 31 to laterally offset relative to the fixed adsorption units 3, so as to realize that the manipulator can stably grasp the back panels of different sizes of TV sets.

[0018] As Figure 1 shown in the figure, the adsorption unit bracket 2 includes a pair of mounting arms 21 and a connecting arm 22 that are parallel in the horizontal direction. The two mounting arms 21 are connected by the connecting arm 22. In order to ensure the stability of the adsorption unit bracket 2 during operation, the connecting arm 22 connecting the two mounting arms 21 is provided with two or more, and these connecting arms 22 are arranged parallel to each other; the fixed adsorption unit 3 is fixedly connected to the mounting arm 21 through an adjusting arm 321, and the fixed adsorption unit 3 can adjust the position fixedly connected to the mounting arm 21 according to the size of the back panel of the TV set; in order to reduce the overall weight of the manipulator 1 and the load of the robotic arm, the mounting arm 21 is made of aluminum alloy profile.

[0019] As Figure 3 shown in the figure, the connecting arm 22 includes an adjusting plate 221 and a mounting plate 222. The two adjusting plates 221 are respectively fixedly connected to both ends of the mounting plate 222 through a right-angle mounting plate 223, and fixing plates 2221 corresponding to the right-angle mounting plate 223 are fixedly arranged at both ends of the mounting plate 222; an adjusting groove 2211 is arranged on the adjusting plate 221, and the mounting arm 21 is locked on the adjusting groove 2211 of the connecting arm 22 through bolts and nuts. The structure of the adjusting groove 2211 enables the distance between the two mounting arms 21 to be adjusted according to the width of the back panel of the TV set; the mounting plate 222 is connected to the end of the robotic arm.

[0020] As Figure 4 shown in the figure, the fixed adsorption unit 3 includes an adjusting arm 321, a connecting rod 322 and an adsorption head 323; a connecting rod hole 3212 for detachably and fixedly connecting with the connecting rod 322 is arranged at one end of the adjusting arm 321; an installation groove 3211 is arranged on the adjusting arm 321, and the installation groove 3211 is locked on the mounting arm 21 through bolts and nuts. The fixed adsorption unit 3 can adjust the installation position relative to the mounting arm 21 according to the width of the back panel of the TV set; the lower end of the connecting rod 322 is fixedly connected with an adsorption head 323, and the adsorption head 323 can be an electromagnetic iron, a vacuum chuck, a vacuum generator and other components that can generate an adsorption force on the back panel of the TV set.

[0021] AsFigure 2 As shown, the adsorption unit offset device 4 includes a guide rail 41, a telescopic device 42, and a slider 43; both the telescopic device 42 and the guide rail 41 are parallel to the mounting arm 21; the slider 43 is relatively fixed to the mounting arm 21, the guide rail 41 is slidably engaged with the slider 43, and the guide rail 41 reciprocates on the slider 43; a connection structure 44 is fixed to one end of the guide rail 41, and a floating adsorption unit 31 is fixedly connected to the connection structure 44. The telescopic rod 45 of the telescopic device 42 is synchronously connected to the guide rail 41 through a synchronous plate 49. The telescopic device 42 can drive the guide rail 41 with the floating adsorption unit 31 to slide on the slider 43 according to the size of the TV back panel, so as to realize the lateral offset of the floating adsorption unit 31 relative to the fixed adsorption unit 3.

[0022] The slider 43 is fixedly installed on the mounting base 46, and the mounting base 46 is fixed to one end of the mounting arm 21, so as to realize the relative fixation between the slider and the mounting arm 21; a telescopic device fixing plate 48 is also fixedly arranged on the mounting base 46. The telescopic device 42 is fixedly connected to the mounting base 46 through the telescopic device fixing plate 48. The telescopic device fixing plate 48 is an "L"-shaped plate. The horizontal surface of the telescopic device fixing plate 48 is fixedly connected to the mounting base 46 by bolts, and a fixing hole coaxial with the telescopic device 42 is opened on the vertical surface. The telescopic device 42 passes through the fixing hole and is fixedly arranged on the mounting base 46.

[0023] Because during the installation process, some minor deviations will inevitably occur. For example, the telescopic direction of the telescopic rod 45 of the telescopic device 42 is not strictly parallel to the guide rail 41, which may cause the guide rail 41 to get stuck when sliding on the slider 43, thus unable to complete the lateral offset of the floating adsorption unit 31 relative to the fixed adsorption unit 3. Therefore, the connection between the end of the telescopic rod 45 of the telescopic device 42 and the synchronous plate 49 is connected by an elastic column 47, so as to ensure that the slight deviation in parallelism between the telescopic device 42 and the guide rail 41 during the installation process will not affect the sliding of the guide rail 41 on the slider 43; a displacement sensor is arranged on the telescopic device fixing plate 48 to detect the distance between the telescopic device fixing plate 48 and the synchronous plate 49, so as to ensure that the telescopic device 42 drives the guide rail 41 with the floating adsorption unit 31 to just slide to the position corresponding to the size of the TV back panel on the slider 43, and avoid the lateral offset distance of the floating adsorption unit 31 relative to the fixed adsorption unit 3 being too large and exceeding the range of the TV back panel; the telescopic device 42 can be an electric telescopic device, a pneumatic cylinder, a hydraulic cylinder, or other elements that can perform telescopic movement.

[0024] The above is the preferred embodiment described in the present invention. It should be noted that: for those of ordinary skill in the art of this technology, without departing from the principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as within the protection scope of the present invention.
